Spectre is a SPICE-class circuit simulator owned and distributed by the software company Cadence Design Systems. It provides the basic SPICE analyses and component models. It also supports the Verilog-A modeling language. Spectre comes in enhanced versions that also support RF simulation (SpectreRF) and mixed-signal simulation (AMS Designer). A massively parallel version, Spectre X, was also released to provide performance gains while maintaining the same accuracy as previous Spectre versions.[1]

1. Spectre and SPICE netlist formats
2. Spectre, SPICE, and PSpice models
3. Verilog-A 2.0 LRM-compliant behavioral models and structural netlists
4. DSPF/SPEF parasitic formats
5. S-parameter data files in Touchstone, CITI-file, and Spectre formats
6. SST2, PSF, PSF XL, and FSDB waveform formats
7. Digital vector (VEC), Verilog-Value Change Dump (VCD), Extended Verilog-Value Change Dump (EVCD), and digital stimulus

## History

Spectre was developed at Cadence Design Systems by Ken Kundert and Jacob K. White.
